title: Prognostic factors for open globe injuries and correlation of ocular trauma score at a tertiary referral eye care centre in Singapore.
abstract: OBJECTIVE
  To evaluate the factors influencing final vision outcome after surgical repair of open globe injuries and to correlate the Ocular trauma score.
  
  
  METHODS
  Retrospective case analysis of patients with open globe injuries at a tertiary referral eye care centre in Singapore was performed. Pre-operative factors affecting final vision outcome in patients with open globe injury and correlation of ocular trauma score in our study with international ocular trauma scoring system was performed.
  
  
  RESULTS
  Case records of 172 eyes with open globe injury were analyzed. Mean age was 36. 67 years. Mean follow up was 12.26 m. Males were pre-dominantly affected. Initial visual acuity was ≥ 20/40, 20/50 < 20/200, 20/200- CF, HM- PL and NLP in 24 (14%), 39 (22.7%), 16 (9.3%), 66 (38.4%) and 27 (15.7%) eyes respectively. Final visual acuity was ≤ 20/40, 20/50 < 20/200, 20/200- 1/200, HM- PL and NLP in 76 (44.2%), 28 (16.3%), 11 (6.4%), 30 (17.4%) and 27 (15.7%) eyes respectively. Ocular trauma score in our study correlates with international ocular trauma scoring system.
  
  
  CONCLUSIONS
  The present study showed pre-operative variables such as mode of injury, pre-operative visual acuity, traumatic cataract, hyphaema, relative afferent papillary defect, vitreous lossand vitreous hemorrhage to be adversely affecting the final vision outcome. Our study showed a good synchrony with international ocular trauma score (OTS) and based on this study we were able to validate application of OTS in Singapore population. Recognizing these factors can help the surgeon in evidence based counseling.
